However, no validated Arabic version has been available, limiting standardized assessment in Arabic-speaking populations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This prospective cross-sectional validation study translated and culturally adapted the SFI into Arabic (SFI-AR) following internationally accepted guidelines, including forward and back-translation, expert committee review, and pilot testing. Adults aged \u226518 years with spinal pain or dysfunction completed the SFI-AR and the Arabic Chronic Pain Grade Scale (CPGS-AR). A clinically stable subgroup repeated the SFI-AR after 5\u201310 days. Psychometric evaluation assessed interpretability, internal consistency, test\u2013retest reliability, measurement error, structural validity using exploratory and confirmatory factor analyses, and convergent validity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 411 patients were included, with 137 completing the retest.

Measurement error was low (SEM 4.27; MDC 12.56). No significant floor or ceiling effects were observed. Exploratory factor analysis supported an essentially unidimensional structure, explaining 48.29% of the variance, and confirmatory factor analysis showed acceptable fit for a single-factor model (CFI\u2009=\u20090.905; TLI\u2009=\u20090.896; RMSEA\u2009=\u20090.073; SRMR\u2009=\u20090.065).
